A new genus and species of snakes was described by the Russian and Vietnamese scientists based on the type material from Loc Bac forest, Lam Dong Province.
The new genus was named Coluberoelaps Orlov, Kharin, Ananjeva, Nguyen & Nguyen, 2009. This name is originated from a combination of two generic names: Coluber (type genus of the family Colubridae) and Elaps (type genus of the family Elapidae) due to the morphological features of the new genus are similar to the diagnoses of both above snake families.
Species name was given after the name of Dr. Nguyen Van Sang from the Institute of Ecology and Biological Resources in Hanoi, in recognition of his outstanding contributions towards herpetology in Vietnam.
